A hare and a tortoise compete in a race over a straight course 1.00 km long. Thetortoise crawls at a speed of 0.200 m/s toward the finish line. The hare runs at a speedof 8.00 m/s toward the Finish line for 0.800 km and then stops to tease the slowmoving tortoise as the tortoise eventually passes by. The hare waits for a while afterthe tortoise passes and then runs toward the finish line again at 8.00 m/s. Both thehare and the tortoise cross the finish line at the exact same instant. Assume bothanimals, when moving, move steadily at their respective speeds. (a) How far is thetortoise from the finish line when the hare resumes the racer (b) For how long in timewas the hare stationary?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
